Review on Master Massage Vibration Attachment Giftbox by Katie Miller

Purchased in March before the start of the summer training season. I didn't use it much initially because the workout hadn't started yet, but once May rolled around I liked how long it lasted on a single charge. The second charge didn't last as long, but I didn't notice it. After the 3rd full charge, it turns on immediately and stops. Now it won't turn on. Used about 10-15 times and it's unusable. If the seller recommends me a replacement, I'd be happy to try again and change this rating.
